This should go into the Weaponlight collection thread.
But yes I have one. I got mine on clearance/close out from LAPOLICEGEAR.com. I paid $160.
Apparently mine is a rare variant. It is a M952P not the M952XM. there were M952P and M952C available before the XM versions
the M952P came with the rare SW01 tailcap which you see below, "P" stands for pressure.
The M952C came with the SW02, "C" stands for clickie.
Mine is a rare oddity since the SW01 is so old, yet it was bundled with the newer style M2 head on the new M952 body. Mine was sealed in the box when I bought it.
I see yours has the new M93 rail attachment, compared to the old style swan lever mount that I have. and the crappy thumb screw versions. I hate the thumb screws. Also you have the newer LU60 adapter, see mine is hexagonal wheras yours looks like semi-circles were cut out to facilitate better finger grip for unscrewing it off the bezel.
In terms of using a Malkoff, I have not tried it yet as I dont have a malkoff yet. I do notice that the LU60 adapter doesnt fit dropins very easily. the M2 head has a bit of a buffer due to the shock absorbing head. You may want to check with Malkoff or other M952 owners if a Malkoff will fit. also you should get a HA C2 head (only $25 on optics planet) and use that style head with the M952. slimmer and no need for the copper ring needed for the M2 head.
